. A sanitary landfill has available space of 16.2 ha at an average depth of 10 m. Seven hundred sixty-five (765) cubic meters of solid waste are dumped at the site 5 days per week. This waste is compacted to twice its delivered density. Draw a mass balance diagram and estimate the expected life of the landfill in years.

An MSW landfill has inactive cells covered with an intermediate cover of 1 m of sandy-loam soil. The soil is washed before use, thus it is at 100% field capacity when applied. The local 10-year average weather data is as follows.

To treat solid waste generated from a town of population 80000, a landfill is designed. The per capita solid waste generation is 1.8 kg/day/person and density of compacted solid waste is 1250 kg/m3. The solid waste cover factor is 3.0. Estimate the area of landfill required in hectares for 15 years of operation. Assume depth of landfill as 5 m.
